Abstract
The sensor guide wire assembly having a sensor element is inserted into the patient's body. Acoustic or electromagnetic waves are then emitted from an external source toward the senor element. The sensor element receives the incident waves and enters into a resonating state. The characteristics of the resonance correspond to the variable or variables to be measured. A transducer is located externally from the patient's body and receives the scattered wave and transmits a resultant signal to an electronic drive and detection unit for signal analysis.
